A computerized device designed to help police determine whether a person is under the influence of alcohol or drugs is being tested in Monrovia.
The $20,000 computer, called EM/1, was demonstrated at Tuesday's City Council meeting. It is the first of its kind in the nation, Police Chief Joseph Santoro said.
The computer records the eye movements of motorists who have been stopped for investigation of drunk driving. The suspect looks into a screen and is told to watch a flashing green light.
Drivers' eye movements and the dilation or constriction of their pupils are viewed to determine whether they are under the influence of alcohol or a variety of drugs.
